   site.css - shared styling for the public content pages of roofexa.com
   (/about, /contact, /support, /privacy, /terms).

   Same design language as the marketing landing (public/home.html) and the app
   (public/css/app.css): green brand, purple as a sparing accent, slate ink,
   light theme, Inter + JetBrains Mono, mono kickers and hairline rules.

   home.html keeps its own inline stylesheet on purpose - it is the one page we
   never want to risk on a shared-CSS edit. Tokens below are copied from it.
